BILGE-PUMP.

SPECIFICATION forming part of Letters Patent No. 394,725, dated December18, 1888.

Application tiled March 16, 1888.

To all '1L/'hom t may concern:

Be it known that I, NATHAN RICHARDSON, a citizen of the United States,residing at Little Falls, in the county of Morrison and State ofMinnesota, have invented certain new and useful Improvements in the Modeof Removing' Bilge-later from Vessels of all Sizes or Dimensions; andIdo declare the following' to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which itappertains to make and use the same, reference bein had to theaccompanying' drawings, and to the letters and figures of referencemarked thereon, which it'orm a part of this specification.

My invention is a new bilge-water pump; and it consists in the novelconstruction and arrangement of its parts, as hereinafter described, soas to accomplish the object for which it is designed with greaterdispatch and certainty than any device heretofore made for the purposeof extracting' the bilg'e-water from vessels of any size or materialthat move upon water.

The various parts of my said bilge-\\'ater pump are shown in theaccompanying' drawings, in which- A Figure l is a sectional eli-vationof my pump placed in the bottom of a vessel. Fig. 2 is an elevation ofmy pump removed from the vessel. Fig'. 3 is a rear sectional view ot'Fig. 2, cut on the line w n'. Fig'. 4 is an edge view of the valve-barprovided with the valves and stop-plates Fig. 5 is a top view of Fig. 2,the same being cut ottl at the line x Fig. (i is a view of the valvesand stops, looking down on them through the tube A, said tube being' cutot'f at 1/ y.

My invention is described as l'ollows:

A is a round hollow tube of desired diameter and length and ofsubstantial materialsuch as copper, steel, or gutta'percha-which, whenin place, stands upright in and through the bottom of a vessel, whichmay or may not reach into the water below, the lower end of which isturned in sut'ticiently to form a shou lder, o, against which the valvesu. on the inside ot itmay be pressed down and entirely close it up onthe bottom, and that portion of it which extends above the vessel isperforated, so that the water inside the ves- Serial No. 267,334. (Nomodel.)

sel may pass into said tube and out of the vessel.

I3 is a tube just large enough to slide on over said tube A easily, iscut square across at the upper end, and the other cut diagonallydownwardly from near the upper end to a point about double its diameteron the front side, regardless ot' its size. It might vary some from thisproportion in the length of the two sides. For instance, if the tube Bshould be four inches in diameter, the longer side,

when eut .ready for use, should be nearlyy eight inches longer than theshort side. However, the longer the bevel the greater would be itspower. This tube B has fastened to it two rods, C, passing' up throughthe flange D, one attached to its short and the other to its long side,by which rods it is drawn up when not in use, so that no part of it isbelow the guard J, or the bottom of the boat if the guard is not used.Then in use, itis pressed down nearly its whole length into the waterbelow the said guard or bottom of the vessel, with its longest sidetoward the bow of the vessel, in which position it is firmly held bysaid rods C until such time as it is desired to draw it up out of thewater. This tube may also be made of any suitable material.

D is a flange, to which is firmly attached tube A near its upper end,and which isl screwed down on the top of the pump-house E, and someflexible water-tight material is placed under it to prevent leakage, andthrough which the two rods pass.

F is a fiat bar of iron or of other suitable material, as broad as thediameter of the tube A, and of sufficient thickness to make it sufficiently strong for the use to which it is put, and sufficiently narrowthat it may pass into said tube. At the lower end of said bar are.hinged two valves, c', each a half-circle, which are so arranged thatwhen drawn up a proper distance from the bottom of the tube they fallopen, and when they are pressed against tlang'e c said tube is entirelyclosed. They are self-acting, opening when water is'passing out ot' thevessel and closing water-tight when the vessel is not in motion. Thesaid valves are hinged-one on each side of said bar F-and have attachedto their upper face arms u?, the extreme ends of which IOO turn over thestops a3, and are thereby prevented from falling elose together, butstand at an angle, so that when the water presses up against theln` theysluit upward and close the said tube.

C (l are two rods, whieh pass through the llange D, and are made fast tothe tube lbelow and serve to lower and raise the same to the desiredposition, and on which small stops c are placed to prevent said rods:from being run down too far, and at the point where these rods passthrough flange l) paeking is secured in proper packing-boxes, to preventleaking and to sustain said rods from dropping down of their own weight.

(l are stops held by a. spring, g, and rest against the upper plate, K,and prevent the said bar F from beingI drawn up too far or eomin out-ofthe tube; but by holdin said spring baelc said bar may be taken entirelyout.

ll is a pivoted rod, on whieh are secured two arms, 7L 71.. The upperone eatohes under the ine-lined shoulder 7a2 on the bar l? and holdssaid bar and valves of up above shoulder a in the lower end of tube A,and the lower one, 71.', oatehes over the upper inclined shoulder, 71,and holds the said bar down and presses said valves down tightly againstsaid shoulder. The said valves a are self-acting and are pivoted to thefiat bar l at its extreme lower end, and are opened and Closed by theaetion of the water upon them-opening when raised from the bottom ot'the tube when the vessel is in motion and elosing when the vessel is atrest.

It would require a eonsid erable bloeking up in a thin-bottom vessel tomake room to draw up the tube l, that is slid down and drawn up out ofthe water, so thatthe water would be quite a depth in the bottom of avessel before it could run out through perforated holes over the lian gelf) and near the top of the tube; so l have thought best to have thetube'A perfm'ated down as low as the inside surface of the bottom of thevessel and leave a gateway, e, in the -pump-house E at its bottom, sothe water oan pass in and out through the said perforations. In order toprotect the said tube A and the perforations therein, a sliding gate,e', is dovetailed in said gateway, to be opened and elosed atwill. lplaee on the bottom of the vessel an iron guard, J, that leaves a hollowplace between it and the vessel. The end toward the bow is brought to apoint, and it widens as it runs back, leavin a space under it and anopening at the end in front of and nearly und mneath the tube A. VThisiron guarlfl will suoli the water from the boat the same as the beveledtube l, and may be used Vin Connection with it. rlhis guard should bevery strong and tirmlv fastened to the bottom of the vessel by heavyscrews or bolts, so that it would stand to run through a sand-bar or torun over logs or snags in a river.

lVhen l deem it necessary, and partieularl y where my pump to be used onshallow waters, l proteet the lower end of the pipeA by a wire se'reen,and the gateway in the pumphouse may be proteetetl i n the same way.YFor river boats and vessels used in shallow waters AI use my pump asabove described, exeept the tube l. ln sueh boats l bring the lower endof the tube A Ano lower down than the lowest i surface of thebotttnn ofthe. boat, and in plaee of the tube l, l use a bar, N, ot' spring-steelor other material that is flexible. l :fasten one end to the bottom ofthe boat in frontof the tube A, the other end exteliding downward ashort d istanee into the water, which will ereate a vaoiuim and causethe water to run out ol' tube A. This spring (represented bythe dot tedlines is thus left free, so that when it strikes a bar or otherobstruetion itis pressed back up against the bot-tom of the boat andsprings baelc into position when the obstruetion is passed over. Thisbar of spring-steel maybe hinged to the bottom oli' the boat and made tostand straight down by the use ol' any springing etmtrivanee generallyused for sueh purposes. 'When said sp1-ing is used, the tube A used insueh boats may not extend quite to the lowest surfaee of the same, butroom suliieient may be left that enough may be out out of the bottom toallow the said spring and other material attached to it to bury itselfwhen the boat is aground, passing over a sand-bar or other obstruction;or, instead of taking any portion out of the bottom of the vessel 'forsaid sprngtobu ry itself into, pieces of plank maybe seeured along eaehside of said spring lengtluvse the boat of suiftieieiit length andthiekness for the spring' to bury itself between. Now, when I use thisspring instead of the tube A, l may or may not use the guarlfl J.
